<h2>Detailed Description</h2>
<p>The Q3HBox widget provides horizontal geometry management for its child widgets.</p>
<p>All the horizontal box's child widgets will be placed alongside each other and sized according to their <a href="qwidget.html#sizeHint-prop">sizeHint</a>()s.</p>
<p>Use <a href="q3frame.html#margin-prop">setMargin</a>() to add space around the edges, and use <a href="q3hbox.html#setSpacing">setSpacing</a>() to add space between the widgets. Use <a href="q3hbox.html#setStretchFactor">setStretchFactor</a>() if you want the widgets to be different sizes in proportion to one another. (See <a href="layout.html">Layouts</a> for more information on stretch factors.)</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="Q3HBox"></a>Q3HBox::Q3HBox ( <a href="qwidget.html">QWidget</a> * <i>parent</i> = 0, const char * <i>name</i> = 0, <a href="qt.html#WindowType-enum">Qt::WindowFlags</a> <i>f</i> = 0 )</h3>
<p>Constructs an hbox widget with parent <i>parent</i>, called <i>name</i>. The parent, name and widget flags, <i>f</i>, are passed to the <a href="q3frame.html">Q3Frame</a> constructor.</p>
<h3 class="fn"><a name="Q3HBox-2"></a>Q3HBox::Q3HBox ( bool <i>horizontal</i>, <a href="qwidget.html">QWidget</a> * <i>parent</i>, const char * <i>name</i>, <a href="qt.html#WindowType-enum">Qt::WindowFlags</a> <i>f</i> = 0 )&nbsp;&nbsp;<tt> [protected]</tt></h3>
<p>Constructs a horizontal hbox if <i>horizontal</i> is TRUE, otherwise constructs a vertical hbox (also known as a vbox).</p>
<p>This constructor is provided for the <a href="porting4.html#qvbox">QVBox</a> class. You should never need to use it directly.</p>
<p>The <i>parent</i>, <i>name</i> and widget flags, <i>f</i>, are passed to the <a href="q3frame.html">Q3Frame</a> constructor.</p>
<h3 class="fn"><a name="setSpacing"></a>void Q3HBox::setSpacing ( int <i>space</i> )</h3>
<p>Sets the spacing between the child widgets to <i>space</i>.</p>
<h3 class="fn"><a name="setStretchFactor"></a>bool Q3HBox::setStretchFactor ( <a href="qwidget.html">QWidget</a> * <i>w</i>, int <i>stretch</i> )</h3>
<p>Sets the stretch factor of widget <i>w</i> to <i>stretch</i>. Returns true if <i>w</i> is found. Otherwise returns false.</p>
